RE:RE:RE:Trade Show in BrazilThis "Tradeshow" looks like a Dermatology conference. If it runs like they do it here in the US, https://www.aad.org/meetings/annual-meeting run by the academy of dermatology and Pharma and Medical device companies display there.
The Academy of Dermatology would promote the conference and companies pay for floorspace to display their products. Cost relates to how large your space is and how many people are working the conference.
It could provide good exposure, at the end of the day success usually depends on contacts and execution.
I hope they are successful
